The boat-tailed grackle (Quiscalus major) is a passerine bird of the family Icteridae found as a permanent resident on the coasts of the Southeastern United States.
The boat-tailed grackle is found in coastal saltwater marshes and, in Florida, also on inland waters.[ citation needed ] In salt marsh areas, least bitterns will often associate with and make mixed colonies with grackles. [2] Boat-tailed grackles have established significant populations in several United States Gulf Coast cities and towns, [ citation needed ] where they can be found foraging in trash bins, dumpsters, and parking lots.
The nest is a well-concealed cup in trees or shrubs near water; the average clutch size is just over three eggs. [3]
The male boat-tailed grackle is 37–43 cm (15–17 in) long and weighs 165–250 g (5.8–8.8 oz). [4] Adult males have entirely iridescent black plumage, a long dark bill, a pale yellowish or brown iris, and a long keel-shaped tail. The adult female is much smaller at 26–33 cm (10–13 in) long and a weight of 90–115 g (3.2–4.1 oz). [5] She is also distinguished by her shorter tail and tawny-brown coloration, which covers the body apart from the darker wings and tail. The wingspan in adult birds is 39–50 cm (15–20 in). [6] In standard measurements, this species measures 13–20 cm (5.1–7.9 in) along the wing bone, 11–20 cm (4.3–7.9 in) in tail length, 2–4.2 cm (0.79–1.65 in) along the culmen, and 3.6–5.8 cm (1.4–2.3 in) along the tarsus. [7] On average, the boat-tailed grackle weighs about 10% more than the closely related great-tailed grackle, although the male great-tailed grackle has an even longer tail. [7] [8]
Young males are black but lack the adult's iridescence. Immature females are duller versions of the adult female and have blotches or spots on the breast. The eye color of the boat-tailed grackle varies with range. Gulf Coast and inland birds have dark eyes, whereas Atlantic birds have pale eyes. [9]
The boat-tailed grackle was first described by French naturalist Louis Pierre Vieillot in 1819. Its specific epithet major means "larger" in Latin. Despite its restricted range, there are four subspecies of the boat-tailed grackle, differing in size and iris color. The boat-tailed grackle was once considered the same species as the great-tailed grackle. The great-tailed species is generally quite similar of slightly smaller body size but has a longer tail and lacks this species' distinct domed head shape. The common grackle, with which the boat-tailed species often overlaps along the Atlantic coastline, is noticeably smaller and shorter-tailed, as well as lacking the domed head shape.

They forage on the ground, in shallow water, or in shrubs; they will steal food from other birds. They are omnivorous, eating insects, minnows, frogs, eggs, berries, seeds, grain, and even small birds.[ citation needed ]
Its song is a harsh jeeb, and it has a variety of typically grackle-like chatters and squeaks.
The American bittern is a species of wading bird in the heron family. It has a Nearctic distribution, breeding in Canada and the northern and central parts of the United States, and wintering in the U.S. Gulf Coast states, all of Florida into the Everglades, the Caribbean islands and parts of Central America.
The American white ibis is a species of bird in the ibis family, Threskiornithidae. It is found from the southern half of the US East Coast, along the Gulf Coast states and south through most of the Caribbean coastal regions of Central America. This particular ibis species is a medium-sized wading bird, possessing an overall white plumage with black wing-tips, and having the typical downward-curving bill of the ibises, though of a bright red-orange color, the same hue as its long legs. Males are larger and have longer bills than females. The breeding range runs along the Gulf and Atlantic Coast, and the coasts of Mexico and Central America. Outside the breeding period, the range extends further inland in North America and also includes the Caribbean. It is also found along the northwestern South American coastline in Colombia and Venezuela. Populations in central Venezuela overlap and interbreed with the scarlet ibis. The two have been classified by some authorities as a single species.
Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera Botaurus and Ixobrychus are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus Zebrilus, form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks.
The killdeer is a large plover found in the Americas. It gets its name from its shrill, two-syllable call, which is often heard. It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. Three subspecies are described. Its upperparts are mostly brown with rufous fringes, the head has patches of white and black, and two black bands cross the breast. The belly and the rest of the breast are white. The nominate subspecies breeds from southeastern Alaska and southern Canada to Mexico. It is seen year-round in the southern half of its breeding range; the subspecies C. v. ternominatus is resident in the West Indies, and C. v. peruvianus inhabits Peru and surrounding South American countries throughout the year. North American breeders winter from their resident range south to Central America, the West Indies, and the northernmost portions of South America.
The piping plover is a small sand-colored, sparrow-sized shorebird that nests and feeds along coastal sand and gravel beaches in North America. The adult has yellow-orange-red legs, a black band across the forehead from eye to eye, and a black stripe running along the breast line. This chest band is usually thicker in males during the breeding season, and it is the only reliable way to tell the sexes apart. The bird is difficult to see when it is standing still, as it blends well with open, sandy beach habitats. It typically runs in short, quick spurts and then stops.
The long-billed dowitcher is a medium-sized shorebird with a relatively long bill belonging to the sandpiper family, Scolopacidae. In breeding plumage, adults are characterized by a beautiful rufous head and underparts with a darker mottled back and a large white upper rump only seen in flight. They feed in various freshwater habitats with their bill underwater in a "sewing machine" motion and are known to have an exciting mating display where males chase females in flight. The genus, Limnodromus is Ancient Greek from limne, "marsh" and dromos, "racer". The specific scolopaceus is Neo-Latin for "snipe-like", from Latin scolopax, scolopacis, a snipe or woodcock. The English name is from Iroquois and was first recorded in 1841.
The broad-winged hawk is a medium-sized hawk of the genus Buteo. During the summer, some subspecies are distributed over eastern North America, as far west as British Columbia and Texas; they then migrate south to winter in the Neotropics from Mexico south to southern Brazil. Other subspecies are all-year residents on Caribbean islands. As in most raptors, females are slightly larger than males. Broad-winged hawks' wings are relatively short and broad with a tapered, somewhat pointed appearance. The two types of coloration are a dark morph with fewer white areas and a light morph that is more pale overall. Although the broad-winged hawk's numbers are relatively stable, populations are declining in some parts of its breeding range because of forest fragmentation.
The common grackle is a species of large icterid bird found in large numbers through much of North America. First described in 1758 by Carl Linnaeus, the common grackle has three subspecies. Adult common grackles have a long and dark bill, pale yellow eyes, and a long tail. Adults often have an iridescent appearance on their head, especially males. Common grackles can be found widely across North America east of the Rocky Mountains.
The scarlet tanager is a medium-sized American songbird. Until recently, it was placed in the tanager family (Thraupidae), but it and other members of its genus are now classified as belonging to the cardinal family (Cardinalidae). The species' plumage and vocalizations are similar to other members of the cardinal family, although the Piranga species lacks the thick conical bill that many cardinals possess. The species resides in thick deciduous woodlands and suburbs.
Ross's goose, formerly Chen rossii, is a white goose with black wingtips and a relatively short neck. It is the smallest of the three white geese that breed in North America. It is similar in appearance to a white-phase snow goose, but about 40% smaller. Other differences from the snow goose are that the bill is smaller in proportion to its body and lacks "black lips". Like snow geese, Ross's geese may exhibit a darker "blue" phase or morph, though this is extremely rare.
The Carib grackle is a New World tropical blackbird, a resident breeder in the Lesser Antilles and northern South America east of the Andes, from Colombia east to Venezuela and northeastern Brazil. There are eight subspecies, of which the most widespread is the nominate subspecies of Trinidad and the South American mainland. This subspecies was introduced to Tobago in 1905 and is now common there.
The great-tailed grackle or Mexican grackle is a medium-sized, highly social passerine bird native to North and South America. A member of the family Icteridae, it is one of 10 extant species of grackle and is closely related to the boat-tailed grackle and the extinct slender-billed grackle. In the southern and southwestern United States, the grackle is sometimes referred to simply as a "blackbird" or (erroneously) a "crow" due to its glossy black plumage; however, grackles form their own unique genus that is separate from other "blackbirds", such as the red-winged and Brewer's blackbirds, despite being in the same family (Icteridae). Superficially, Brewer's blackbird is one of the most visually similar species to grackles.
The golden-fronted woodpecker is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found in the southern United States, Mexico and parts of Central America.
Grackles is the common name of any of 11 species of passerine birds native to North and South America. They belong to various genera in the icterid family. In all the species with this name, adult males have black or mostly black plumage. Baby birds use a screech-like call to indicate they wish to feed.
The Greater Antillean grackle is a grackle found throughout the Greater Antilles, as well as smaller nearby islands. Like all Quiscalus grackles, it is a rather large, gregarious bird. It lives largely in heavily settled areas.
The Hispaniolan woodpecker is a medium-sized woodpecker endemic to the Caribbean island of Hispaniola.
The Nicaraguan grackle is a species of passerine bird belonging to the genus Quiscalus, a genus of grackles in the New World blackbird family, Icteridae. It is found only in Nicaragua and northernmost Costa Rica.
The slender-billed grackle is an extinct species of grackle in the Icteridae family of birds. The species was closely related to the western clade of the great-tailed grackle, from which it diverged quite recently, around 1.2 million years ago. It weighed 2.5 oz to 5 oz.
Nelson's sparrow is a small New World sparrow.
The short-tailed hawk is an American bird of prey in the family Accipitridae, which also includes the eagles and Old World vultures. As a member of the genus Buteo, it is not a true hawk and thus also referred to as a "buteo" or "buzzard". The white-throated hawk is a close relative and was formerly included in the species B. brachyurus.
